Abstract (en)
The present invention relates to a pressure sensor for a pipe and a method to measure pressure in a pipe non-invasively. The pressure sensor comprises a flexible strip (1), at least one strain sensing element (4), and a tensioning device (5, 9, 10). A first end (2) of the strip is configured to pass through a second end (3) of the strip. Between the first end of the strip and the second end of the strip, the strip comprises the at least one strain sensing element. The pressure sensor is configured to attach to a pipe (6), wherein the first end of the strip extends through the second end of the strip. The tensioning device is configured to tension the pressure sensor around the pipe.
